description |
(System: Ubuntu 14.04, up to date packages)
I noticed that unattended-upgrades spends a significant amount of time in phases where it runs at 100% cpu. On a slower machine (core 2 t7200 2GHz) this goes on for minutes rather than seconds. This interferes with using the machine for other tasks.
Using the --debug option to unattended-upgrades shows that the program outputs a lot of lines like the following during these 100% cpu phases:
matching 'a'='trusty-updates' against '<Origin component:'universe' archive:'trusty-updates' origin:'Ubuntu' label:'Ubuntu' site:'de.archive.ubuntu.com' isTrusted:True>
From this output I guess the operation executed is not so complicated that it should require so much cpu power. ??
ProblemType: Bug

ProcVersionSignature: Ubuntu 3.13.0-40.69-generic 3.13.11.10

UpgradeStatus: No upgrade log present (probably fresh install) |
[Impact]
* Unattended-upgrades consumes tens of seconds or even minutes of CPU time to verify the origin of the packages
* Using excessive amount of CPU is unpleasant for desktop/laptop users and also wastes computation time on servers/cloud instances.
* Unattended-upgrades' algorithm for checking and adjusting package origins is redesigned to visit and adjust less packages.
[Test Case]
* The added upgrade-all-security autopkgtest measure the time u-u needs for upgrading security updates on the tested release starting with no security updates applied to the point where all security updates are applied but all packages are left upgradable from <release>-updates. The test also measures the time needed for --dry-run to find no updates to be installed unattended.
* Please run autopkgtests and look for the to time results:
...
All upgrades installed
44.41user 3.06system 0:48.35elapsed 98%CPU (0avgtext+0avgdata 164872maxresident)k
208inputs+192376outputs (0major+642657minor)pagefaults 0swaps
...
No packages found that can be upgraded unattended and no pending auto-removals
2.83user 0.11system 0:02.98elapsed 98%CPU (0avgtext+0avgdata 79308maxresident)k
[Regression Potential]
* Due to algorithm redesign there is a risk that packages from allowed origins are not upgraded. There were unit tests for testing the selection of the right packages to upgrade already, but a new autopkgtest is also introduce to verify u-u's behavior on current real-life security-updates.
